- Beit known thatl, HArrrron P. RHODES,-

.Apitizengof .the UnitedA States, residing at Galveston, in the county of Galveston and State of Texas, have invented certain new and useful 'Im rovements in Piston-Rod Packin rend oA hereby declare the followingto e s full, clear, end-enact description of thel invention, such es will' enable others skilled in the art to which it opper .tsins to make and use the same.

My improved packing consists of smnnber of metal rings 6, formed of s. plnrelity of sections 7, three being shown in the drawings. The rings 6 are formed with fist sides 8 and are used in pairs with the tiet sides opposite each other, as shown in Figs. i, 3

' ring being formed of sections,

metal packing-rings to accoml'i'iodate themselves to the inequality of the transverse movement, andthe leak of steam and springing of the rod is avoided. The pressure of the steam against the inner end of the packing when live steam is on the packing-ring serves' to force the packing rings 6 against the piston rods and also the rings against the sides of the stuffing-box, thns preventing By providing a wide soft-metal or rubber ringbetween cach. pair of complete metal packing members G and narrow soft-rubber rings at the ends of the said metal packing members G the sei/eral complete packing merrbers are sufficiently separated to form the necessary steam-tight joint, and by reason of the nibs c on the packing members the said packing members are held from Acrawling and losing their desired relation with respect to each other.

3.
